Answer : Option A
Explanation :
In chemistry, pH is a numeric scale used to specify the acidity or basicity of an aqueous solution. Explanations with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic. Pure water is neutral, being neither an acid nor basic; so it has pH value of 7.
